Hello.

I am helping a friend's six/6 years (no more warranty obviously) old HP
Pavilion DV6700 notebook/laptop that died yesterday morning. Pressing
power does not show anything. There is still a blue light with the power
AC connected to it, but that's it. No noises, sounds, beeps, anything on
screen, etc. A friend of mine suggested to remove its battery with power
AC connected, and that helps very a little. We now saw all blue lights
blink once on the top of the keyboard, and then it is dead again. Still
no audio, beeps, sounds, noises, etc. We tried removing its 2.5" Hitachi
SATA HDD, but that didn't change anything. We read the online support
about what to try and see. They mentioned patterns, beeps, etc. None of
them match to blue lights blinking once and they seem to point to the
lights near caps and num lock keys which never showed lights. We also
tried holding down the power button for 15 seconds trick. No luck there.

We checked inside a little and things appear to be clean. The only thing
that might look like a problem is its CMOS battery that has red leak(?).
No odor and stuff though. Also, SATA HDD seems OK since I was able to
copy most of his data. However, GSmartControl says there were
reallocation errors so I assume this HDD is dying (also heard clicky
noises at first when connected to an USB2 adapter to copy his data).
Also, he did mention that his laptop/notebook's fans were loud and was
hot, but lately it got quiet. It sounds like it overheated to death.
Vents looked fine. :( I am thinking this notebook/laptop is dead.

What do you think? Old dead one and time for a new one? Thank you in
advance. :)

I don't have the model of computer you cite, but I do have an HP laptop.
Mine is a G72 model. The computer you cite is not new, and may not
justify a LOT of cost to repair. However there are a couple of things I
would suggest you try:

Remove the RAM and clean the contacts with alcohol or a rubber pencil
eraser. RAM that is failing could cause your problem.

The comment about a CMOS battery leak is troubling. Some computers will
not start if the battery voltage is too low. Leaking is not a good
indicator and could mean your battery is bad. Since they cost so
little, it might be worth replacing it if the voltage measures less than
the typical 3 volts.

Having to pay someone for repairing the computer could cost more than it
is worth. I have repaired them, but I have the tools and some knowledge
so it is practical.

What if there is no battery in it? Can it still boot up if power AC is
connected at least? Also, how do you remove its battery? It is like
stuck. We tried to remove it, but its connector came out from the
circuit board. Oops! :(

Yeah. I told him just get a new one since it is six/6 years old and we
got his HDD data copied.

As I mentioned before, SOME computers will not start. I cannot be sure
yours is that way. Just a word of caution.

The AC power really powers the circuit AFTER the CMOS is read. Many
computers look for the reading from the CMOS to be powered by the
battery and THEN allow the AC power to start. Since most use a coin
type battery (CR2032) and they cost only a couple dollars, it is a cheap
way to eliminate this as the cause.

Also, how do you remove its battery? It is like
Post by Ant
stuck.
I am not familiar with this particular computer, but my computer has a
holder that contains the battery and from the terminals of the battery
powers the MB via a two pin wired connector. If you have this type of
setup, then the battery may be replaced the holder. If not, you might
need to buy the assembly rather than replace the coin battery. They are
not hard to find at a Radio Shack or Best Buy.

Do you have a voltmeter so you could measure the battery voltage? If it
measures 3 volts, the battery is probably good. Less than that and it
is in need or replacement.

There is one other item that COULD give you the same symptoms. The
power adapter could be failing to provide enough voltage under load. Do
you know of anyone with a similar computer that has a power adapter that
you could borrow? Measuring the voltage of the adapter disconnected
from the computer is misleading, as the voltage will be higher than when
it is under load.

I would suggest that if you cleaned the RAM contacts, know the CMOS
battery is good, and tried another power adapter, you probably should
not pursue repair on the computer. The cost could become more than it
is worth.

I remember there was a white ring around the battery. We couldn't figure
out to make it let go of the battery. Online manual didn't really answer
how to remove it or match what we saw with its diagram.

Yeah, it's so old now. Might as well get a new one. He is already
researching on a new one.

Some batteries have strips of metal spot welded onto them and then
soldered into the board. If that's what you have, pulling it out
of the board probably did some internal damage that you may not be
able to repair. Having said that, the word "connector" really doesn't
apply to that type of installation.

Well, it is like the one in

didn't show the white plastic(?) holder for the battery.
